Autonomo Spain shares five years of experience with tax guides, tools, services, and clear explanations for freelancers in Spain.
Hi, I’m Adrienne. I’ve been autónoma in Spain for many years, and in this website I’ve put together some of what I’ve learned — and what I wish I’d known or had easy access to when I was starting out. More about me.
Over the years, I’ve worked with all sorts of clients in Spain, Europe and across the world and taken on all kinds of projects during my rather adventurous journey as an autónomo in Spain. Alongside the actual work, I’ve had to learn the ins and outs of the bureaucracy, work with tax deadlines, tracking revenue and expenses, even redoing an invoice or two because I got the format or VAT wrong.
It’s been a massive learning curve, but now I feel like I know what I’m doing, and I thought some of what I’ve picked up might be helpful to you too. So I decided to write it all down.
